Patented March 23, 1909.

Application filed April 2, 1908. Serial No. 424,843.

To all whom it may concern: Be it known that we, thus T. NroKLiN and.JOHN BERGQUIST, citizens of the United States of America, residing atLos An eles, county of Los Angeles, State of Ca ifor- V nia, haveinvented a certain new and useful Glue-Cutting Apparatus, and do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

7 This invention relates to apparatus for cutting glue or other materialof an analogous nature; and has for its object to provide a simple andinexpensive construction in such apparatus which shall operateeffectively in practice to accomplish the purpose for which it isdesigned.

The invention consists of the novel features, and peculiar construction,arrangement and combination of the parts in the apparatus, as broughtout in the following description of one form in which the invention maybe embodied and whichis illustrated in the accompanying drawings formingpart hereof, in which, 7

Figure 1 is a view in perspective, of the apparatus; some of the partsbeing shown broken away. Fig. 2 is apartial longitudinal view showingthe crosshead and follower in section and the weighted catch. 1 Fig. 3is a view, partly in section, of the springpressed iston-valve. Fig. 1is a view taken on the otted line 1-4 of Fig.1. Fig. 5 is a view showingin cross section the shape of the cutting wires. Fig. 6 is a view ofthefluid pressure means mounted on top of the housing at the rear, forraising'and lowering the roof member. Fig. 7 is a view taken on thedotted line 77 of Fig. 6. Fig. 8 is a view, in perspective, of the rearend portion of the roof-member.

Referrin to the drawings, 1 designates the top of a ta le, which top maybe supported in any suitable or approved manner, and comprises arrangedlongitudinally on opposite sides, pieces of framework; whichpieces aremade up of a top-plank 2, a strip 3 preferably of metal suitably securedto the plank, and an angle iron 4 suitably secured in position undersaid plank and strip and separated therefrom, preferablyby-"interposedferrules 5. The strips '3 are disposed to have a portion thereof projectinwardly between the top planks 2 to constitute a way whereon a traycarrying material may travel.

Mounted at the rear on the top of a table andat right angles thereto isa frame 6 provided with stretched cutting wires 7 extend- "ingbetweenits sides, each of said wires being formed and arranged in the frame topresent an edged face tothe front. (See Fig. 5).

Abutting the frame 6 and extending forwardly thereof is a housing 8comprising upright walls 9,.e'ach suitably secured in position onframe-pieces 1, and a roof member 10 fitting between and pivoted in thewalls at the forward end thereof.

To provide automatic means for lowering and raising the roof member 10,it may be pivotally connected. at its rear end to a link 11, and.thereby be operatively associated with the fluid-pressure motor 12,through the intermediary friction holding-device 13. The motor 12. issuitably mounted above the device 13, which in turn is mounted oncross-piece 14 secured to walls 9 of the rousing. The device 13comprises a casing 15 inwhich is arranged the parts 16 of a splitcylindrical block having upper and lower central longitudinal openingstherein, which openings taper toward and communicate with a recessedportion 17. The pi ton 18 of motor 12 is connected to rod 19 and aspring 20 is suitably arranged at the lower end of the cylinder of themotor to support the parts when the fluid pressure is removed from thelower end of the cylinder. The lower end portion of rod 19 and the upperend portion of link 11 are tapered respectively and fitted in the upperand lower openings in the split block, and the ends of the rod and linkare each provided with a shoulder 21 fitting in the recessed portion 17of the split rock.

At the rear end of the roof-member is mounted a roller 22, and above theframe 6 a perforated pipe 23 connected to a water supply (not shown) isprovided to allow water to trickle on theframe 6 to moisten the cuttingwires 7 At the .rear end of the table top is arranged, intermediate ofand below the pieces of frame-work 1, the cylinder 2 1 of afluidpressure motor, suitably secured to said pieces of frame-work so asto be carried thereby. To control the movement of the piston 28 incylinder 24, a four-way valve 25 mounted on the table top, is connectedto a suitable source (not shown) of fluid under pressure, and hasconnected thereto pipes 26 and 27 leading respectively to the front andrear ends of the cylinder. The piston 28 is connected by means of rod 29to crosshead 30 which is mounted between the frame pieces 1 and isprovided on each of its sides with a part 31 adapted to fit between thestrip 3 and angle iron 4 and which rests on said angle-iron.

At the rear of the crosshead 30 is a follower 32 comprising afront-board 33 hingedly connected at one end to the crosshead and aback-board 34 slidably mounted 011 the front-board. To constrain thesliding movement of the back-board on the frontboard, a pin 35 fixed onthe back-board is arranged to engage the front-board in a slot 36therein. The back-board 34 is provided at one end with a flange 37 whichcarries pins 38 extending part way into sockets 39 on the front-board,said pins passing through s rings 40 which are interposed between theange and the sockets for a purpose hereinafter mentioned.Cross-connected legs 41 are pivotally connected to the front-board 33 inlugs 42 thereon, and have provided on their free ends toes 43 and 44which are adapted to coact with projections 45 on the crosshead topermit of locking the legs 41 in a raised position, and weighted catches46 are pivoted at suitable points on the framepieces for a purposehereinafter mentioned.

To automatically raise the follower to an upright position there may beprovided at each side of the crosshead 30 a pivotally mounted trigger 47having a part 48 normally bearing against the front-board 33 of thefollower, and a roller 49 suitably mounted on each of frame pieces ofthe table top, in alinement with said trigger.

A small fluid-pressure motor 50 may be associated with the four-wayvalve 25 to operate it in a reverse direction, in which case the pistonrod '51 of the motor may be connected with a crank attached to the lowerendof the movable part of the four-way valve, and the operation of themotor governed by a spring-pressed piston-valve 52 suitably mounted inthe path of the projection 53 on cross-head 30 so that it may beoperated at the limit of the rearward movement of the crosshead. Pipe 54is connected between the source of fluid-pressure supply and the valve52, and pipe 55 leads from the valve to the motor 50.

For the purpose of making an initial cut transversely of the mass ofmaterial when it is desired to divide it into parts of less length thanthat of the whole mass, a swinging frame 56 suitably positioned at thefront end of the table top and having wires 57 stretched therein, may beprovided.

The general construction of the apparatus having been described, themanner of its use and operation will now be explained. Assuming that thecrosshead 30 is in a for\\"ard position and the follower 32 in raisedposition, as shown in Fig. 1. The tray 5S-- shown in Fig. 1 as partlymoved into the housing-with material thereon to be cut is placed betweenthe frame pieces 1 so that the depending side pieces 59 rest 011 the wayprovided by strips 3, and is positioned so that the initial out can bemade by manipulating swinging frame 56; after which the four-way valvemay be operated to move the tray with material thereon into the housing8, the roof member 10 being in raised position. When the tray ofmaterial has been moved to enter the housing the piston passes the mint6 at which is connected the pipe 61 leading to the upper end of thecylinder of motor 12, whereby fluid under pressure causes the piston 18of the motor to move downwardly and consequently the roof-member 10 islowered on the material, whereupon the friction holdingdevice 13prevents farther descent or the raising of the roof-member by pressureexerted on its underside while the material is being moved through thehousing by the follower on the crosshead; since such pressure acts tocause a jamming of the parts 16 of the s lit block against the casing 15as will be readi y understood. The spring-pressed slid ing movement ofthe back-board of the follower permits it to fit snugly against theunderside of the roof-member to prevent material squeezing past it andout of the housing. As the cross-head, and consequently the follower andtray of material in front thereof, move rearwardly through the housing,the material is pressed past the cutting wires 7 in the frame 6; and thetray passing out beneath the frame receives the cut material as itpasses out of the housing. When the cross-head 30 reaches the limit ofrearward movement, the projection 53 thereon operates piston-valve 52whereby the motor 50 operates the four-way valve in a reverse direction;whereupon fluid under pressure is admitted to the rear end of cylinder24, as also to the lower end of the cylinder of the motor 12 throughpipe 62 which is suitably connected with pipe 27. The operation of thevalve 52 thus causes the cross-head 30 to begin its forward movement andcauses the motor 12 to operate to raise the roof-nrember 10. After theroof-member is raised and while the crosshead 30 is moving forwardly,the toes 44 of the follower legs 41, engage the pivoted catches 46,whereby, as will readily be understood, the toes are thrown out ofengagement with the projections 45 so that the follower drops to loweredposition on the crosshead and may pass under a tray of material that maymeantime have. been placed in position at the forward end of the table.When the pressure is removed from the lower end of the cylinder or motor12 the piston 18 is supported by spring 20. It will also be understoodthat the pivoted triggers 47 ride over the rollers 49 near the end ofthe forward stroke and that on the rearward stroke'they, on engagementwith the rollers, cause the movement of the follower to its uprightposition. While a particular description has been given of one form ofapparatus embodying the invention, it is to be understood that it isossible to make various changes and modi- 'l ications, which are Withinthe principle and scope of the invention.
